Product Description

Keep your mission-critical data safe while you’re on the go with the 16TB Aegis Fortress L3 Encrypted Portable SSD from Apricorn. This portable 16TB solid state drive is encased in an aircraft-grade aluminum-alloy shell with an integrated, wear-resistant 10-digit security keypad. The system allows you to set your own pin and transfers data at up to 5 Gb/s over its USB 3.1 Gen 1 connection. Designed to meet FIPS 140-2 Level 3 standards, the drive protects your data with real-time AES-XTS 256-bit encryption. Forced enrollment helps to ensure that the drive can’t be used without programming a PIN, while an auto-lock feature automatically locks the drive after it’s left unattended for a predetermined period of time. The drive is also designed to wipe itself after a set number of incorrect PIN entry attempts.

USB Type-A and USB Type-C cables are included with the drive. The Aegis Fortress L3 is platform agnostic and will work with any complaint system with a powered USB port, including Windows, Mac, Linux, and Android devices.

Designed to Meet NIST FIPS 140-2 Level 3 Requirements

The hard drive, electronics, external fasteners, and the enclosure are all included within this elevated FIPS validation boundary. The tamper-resistant enclosure is milled from a solid block of aircraft-grade 6061 aluminum alloy. Snap-off uni-directional security fasteners are also included in addition to a membrane-style keypad.

Military-Grade Hardware Encryption

Featuring AES-XTS 256-bit hardware encryption, the Aegis Fortress L3 seamlessly encrypts all data as it’s being written to the drive on the fly and it’s designed to protect your data even if the hard drive is extracted from its enclosure.

USB 3.1 Gen 1

USB 3.1 Gen 1 features a maximum throughput of 5 Gb/s. USB 3.1 Gen 1 and USB 3.0 are synonymous.

Software-Free Design

The Aegis Fortress L3 is ready to use right out of the box; no software, drivers, or updates needed. The drive is compatible with Windows, macOS, Linux, or most mass storage-compliant systems with a powered USB port.

Forced Enrollment

The Fortress L3 has no factory-preset default PIN. With forced enrollment, the administrator is required to establish a sufficiently complex PIN before the device can be set up or used.


Create custom profiles and mass configure multiple Aegis devices at once with Apricorn’s Aegis Configurator tool, which is sold separately.

Onboard Keypad

All PIN entries are performed on the device’s keypad, making it compatible with systems without keyboards. The drive shares no critical security parameters with its host computer.

Lock-Override Mode

The Fortress L3 is designated for specific cases in which the drive needs to remain unlocked, such as during reboot, passing the drive through a virtual machine, or other situations that would normally prompt the drive to automatically lock. When enabled, lock-override mode allows the L3 to remain unlocked through USB port re-enumeration and will not re-lock until USB power is interrupted or the lock button is pressed.

Two Read-Only Modes

Particularly important in forensics, read-only mode is ideal for applications that require data to be preserved in its original, unaltered state and can’t be overwritten or modified. The Fortress has two read-only modes. The first is set within the administrator mode and can only be enabled or disabled with the administrator PIN. The second read-only mode can be set and disabled by anyone with a valid PIN.

Data Recovery PINs

In the case of lost or forgotten user PINs, up to four single-use data recovery PINs can be programmed and used to restore access to the data on the drive.

Brute Force Protection

After a predetermined number of consecutive incorrect PIN entry attempts (programmable, up to 20), the L3 will conclude that it is under brute-force attack and will respond by performing a crypto-erase, deleting the encryption key and thus rendering all the drive’s data useless.

Environmental Resistance

Designed with protection in mind, the Aegis Fortress L3’s keypad is resistant to dust, grit, and water. The buttons coated with a durable polymer that defends against surface wear, ideal for preventing hackers from guessing the drive’s most frequently used buttons.

Programmable Minimum PIN Length

For added PIN length and enhanced security, the minimum PIN length requirement can be increased from 7 characters up to 16.

LED Flicker Button Confirm

Indicates positive button entry with visual LED confirmation.

Unattended Auto Lock

Automatically locks after a predetermined amount of time or interruption of USB hub power.

Drive Reset Feature

Offers an infinite number of resets and performs a crypto-erase with new encryption key regeneration.
